Build Your Own Oracle RAC 10g Release 2 Cluster on Linux and Firewire
This super-popular guide from Jeffrey Hunter is now updated for Oracle Real Application Clusters 10g Release 2 and Linux Kernel 2.6 installs. Go for it!
We have 2 node Oracle RAC Cluster. It is running RHEL 5 (2.6.18-92.1.10.el5PAE)
Hardware is HP DL360
We have node eviction issue, Oracle evicts node. It is not very consistent.
Oracle has looked all log files and said this is not Oracle issue but rather system or os issue. Server does not... (7 Replies)

o2cb_ctl - Control program for the O2CB cluster service.
SYNOPSIS
o2cb_ctl -C -n object -t type [-i] [-a attribute ]
o2cb_ctl -D -n object [-u]
o2cb_ctl -I [-o-z] -l manager> [-n object>] [-t type] [-a attribute]
o2cb_ctl -H [-n object] [-t type>] [-a attribute>]
o2cb_ctl -h
o2cb_ctl -V
DESCRIPTION
o2cb_ctl is the control program for the O2CB cluster service. Users are not advised to use this program directly but instead use the O2CB
init service and/or ocfs2console.
OPTIONS -C Create an object in the OCFS2 Cluster Configuration.
-D Delete an object from the existing OCFS2 Cluster Configuration.
-I Print information about the OCFS2 Cluster Configuration.
-H Change an object or objects in the existing OCFS2 Cluster Configuration.
-h Displays help and exit.
-V Print version and exit.
OTHER OPTIONS -a <attribute>
With -C, <attribute> is in format "parameter=value", where the parameter is a valid parameter that can be set in the file
/etc/ocfs2/cluster.conf. With -I, <attribute> may be "parameter", indicating an attribute to be listed in the output, or it may be
"parameter==value", indicating that only objects matching "parameter=value" are to be displayed.
-i Valid only with -C. When creating something (node or cluster), it will also install it in the live cluster. If the parameter is not
specified, then only update the /etc/ocfs2/cluster.conf.
-n object
object is usually the node name or cluster name. In the /etc/ocfs2/cluster.conf file, it would be the value of the name parameter
for any of the sections (cluster or node).
-o Valid only with -I. Using this parameter, if one asks o2cb_ctl to list all nodes, it will output it in a format suitable for shell
parsing.
-t type
type can be cluster, node or heartbeat.
-u Valid only with -D. When deleting something (node or cluster), it will also remove it from the live cluster. If the parameter is not
specified, then only update the /etc/ocfs2/cluster.conf.
-z Valid only with -I. This is the default. If one asks o2cb_ctl to list all nodes, it will give a verbose listing.
EXAMPLES
Add node5 to an offline cluster:
$ o2cb_ctl -C -n node5 -t node -a number=5
-a ip_address=192.168.0.5 -a ip_port=7777
-a cluster=mycluster
Add node10 to an online cluster:
$ o2cb_ctl -C -i -n node10 -t node -a number=10
-a ip_address=192.168.1.10 -a ip_port=7777
-a cluster=mycluster
Note the -i argument.
Query the IP address of node5:
$ o2cb_ctl -I -n node5 -a ip_address
Change the IP address of node5:
$ o2cb_ctl -H -n node5 -a ip_address=192.168.1.5
